The invention discloses an automobile hydraulic buffer. The automobile hydraulic buffer comprises a pipe body, a piston, a piston rod, a spring, a bearing, an oil inlet cavity and a return oil cavity.A damping unit is arranged in the pipe body. The damping unit comprises a base fixed to the interior of the pipe body. A sleeve body is fixed to the base. An extension sleeve is fixed to the sleeve body. The extension sleeve and the piston form motive seal. A core body is embedded in the sleeve body. The core body has the degree of freedom to rotating along the periphery of the axis of the pipe body relative to the pipe body. The damping effect of the buffer is improved. Impact force generated by the spring during extension and contraction is reduced. The comfort ability is improved. Meanwhile, through the structure design of the damping unit, the automobile hydraulic buffer buffers flowing oil, so that the oil flows more stably, the damping stability is improved, and vibration caused byunstable flowing of the oil is reduced.

    本发明公开了一种汽车用液力缓冲器,包括管体、活塞、活塞杆、弹簧、轴承、进油腔以及回油腔;所述管体内设置有阻尼单元,所述阻尼单元包括固定在所述管体内的底座,所述底座上固定有套体,所述套体上固定有延伸套,并与所述活塞动密封,所述套体内嵌有芯体,所述芯体相对于所述套体具有沿着所述管体的轴线周向转动的自由度。本发明提高了该缓冲器的减震效果,降低弹簧往返时产生的冲击力,提高舒适性,同时通过阻尼单元结构的设计,对油的流动进行缓冲,使得油的流动更加稳定,进而提高阻尼的稳定性,降低油流动不稳而导致的振动。
